On top of the thousands of dollars Jack Yacoubian spent to head overseas, a week in London meant a week away from his jewelry business in Franklin.

“That’s going to be a lot of loss, too,” Yacoubian said.

But the gain, the 62-year-old insists, far outweighs it.

Yes, this week will be Yacoubian’s first time in London. And yes, Yacoubian and his wife, Maggie, have plenty of sightseeing lined up, including a day trip to Paris. But this financial commitment was sparked by their interest in the event that will unfold at Wembley Stadium on Sunday (8:30 a.m. CT, CBS).

“We love the Titans and we wanted to go see them play overseas. That was the reason,” Yacoubian said ahead of Tennessee’s game against the Los Angeles Chargers. “My wife and I, we’ve never been to London and we'll spend some time sightseeing and traveling, but we’re here mainly to support the Titans.”

It costs to be a fan

Yacoubian isn’t the only one. Despite the hefty price tag attached to the trip — Yacoubian said his week-long European trip will cost him upwards of $15,000 (about $4,000 for two tickets on a British Airways nonstop flight, $4,500 for hotel accommodations and a few thousand more for food and entertainment) — a steady presence of Titans fans were seen scattered throughout Heathrow airport in the days leading up to the game in London.

Josh Owens, a 37-year-old hospital-case administrator, traveled from Nashville to London with three others on a British Airways direct flight that cost about $2,000 a seat. He’s also paying about $250 a seat at Wembley Stadium for Sunday's game.

For Owens, the appeal of traveling to London was just as big a pull. He had never previously been to England's capital, and had a friend in town he wanted to visit.

“And then when we realized the Titans would also be here around the same time,” Owens said, “I decided to get tickets for the four of us to go to the game.

"We're pretty big Titans fans, and it all kind of just worked out."

Fish and chips

At the game, Owens and anyone else from Nashville can expect something somewhat similar to an experience at Nissan Stadium. Wembley Stadium sells hot dogs, burgers and Budweiser for its NFL games, catering to its audience.

There are some differences, of course. At Nissan Stadium, for example, a cheeseburger with fries costs around $14. At Wembley Stadium, a burger and “chips” costs around £10 (one pound currently converts to approximately $1.32). Oh, and replace hot chicken with fish and chips.

“Have to get that,” Yacoubian said. "We love to try different types of food."

But perhaps the biggest difference? The fans themselves.

A sea of color

“It's rare. You might find all 32 teams represented,” NFL UK managing director Alistair Kirkwood said of the crowd that consistently shows up at Wembley Stadium for NFL games. “Fans will wear jerseys of their favorite teams and then they'll adopt a team for the day.”

That’s more or less what Gary Ashton is expecting.

The official real estate agent of the Titans, Ashton was always going to be enticed by an overseas road trip, but was especially so this time because it meant going back home.

Ashton was born in England in 1961 before moving to the U.S. in 1990. This marks his first time coming back since 1996.

“Full circle,” he said, his homegrown still accent fully intact.

Ashton was efficient in making it happen. He estimated he spent about $1,000 for a flight (making use of his Delta loyalty points), about £1,400 pounds for a week-long stay at an Airbnb (that he'll split with a couple of friends) and about £150 for a seat at Sunday's game (which he purchased through the Titans), which by no means is an easy ticket.

The 90,000-capacity venue is sold out Sunday — just as it was last week, when the Seahawks and Raiders drew a record 84,922 fans at Wembley Stadium in the first "London Week" edition of 2018.

"I don't think it”s gonna be packed with Titans fans," Ashton said, "I think it's just going to be packed with fans of American football from all the teams. You know it's an American spectacle. Quintessentially American. I think its something people (in England) really enjoy. The glitz and glamour, it's always a good production.”

And a good production doesn't come cheap, though that doesn't mean it won't be worth it.

“This will be one trip that we won’t forget,” Yacoubian said, “especially when the Titans win. Hopefully.”
